I'm okay with printing the pointer or similar info but that kind of
trace is pretty ugly. You could trace the pointer when you allocate
the struct, or together with the struct state pointer / the state
parameter in the caller. I guess you can also leave the trace there,
if it says something like:

TRACE("Created parameter evaluator %p.\n", *peval_out);

BTW, notice that you are never checking the return value from
d3dx_create_param_eval(). You should either do that or remove the
return value from the function altogether.
